This application claims priority to U.S. Provisional Patent Application Ser. No. 60/545,383, attorney docket number PVAS0001/MRK, entitled “METHOD AND APPARATUS FOR CONVERTING HUMAN POWER TO ELECTRICAL POWER”, filed Feb. 18, 2004, the entire disclosure of which is incorporated herein in full by reference as if stated in full herein.

FIELD OF THE INVENTION

The field of the present invention is mechanical power converters, and more particularly, machines for converting human-source mechanical power to electrical power.

SUMMARY OF THE INVENTION

The exemplary embodiment of the present invention resembles a stationary bicycle (see, e.g., FIGS. 2C and 2D) without a seat. The exemplary embodiment can be placed in front of a chair in which a person is sitting; the person can place their feet on the exemplary pedals of the exemplary embodiment, and pedal. The exemplary pedals are mounted on respective exemplary pedal arms, which are in turn mounted on opposing ends of a first axle.

The first axle of the exemplary embodiment extends through a center hole in a first geared sprocket wheel. The first geared sprocket wheel has a twelve-inch diameter. One complete revolution of the pedals translates into one complete revolution of the first geared sprocket wheel. In the exemplary embodiment, the pedals and pedal arms are mounted in such a way, and the pedal arms are of such a length, to provide ease of use and lower the torque needed to revolve the first geared sprocket wheel.

When the person pedals, the mechanical motion of the person's pedaling is exerted on the first axle that extends through the first geared sprocket wheel. A sprocket chain connects the first geared sprocket wheel to a second geared sprocket wheel. The second geared sprocket wheel has a diameter that is smaller than the diameter of the first geared sprocket wheel. In the case of the exemplary embodiment, the second geared sprocket wheel has a diameter of seven inches. Because the second geared sprocket wheel's diameter is smaller than the first geared sprocket wheel's diameter, for every revolution of the first geared sprocket wheel, the second geared sprocket wheel makes more than one revolution. In the case of the exemplary embodiment, for every revolution of the first geared sprocket wheel, the second geared sprocket wheel revolves 1.71 times.

The second geared sprocket wheel is mounted on a second axle. The second axle extends through a third gear wheel. The third gear wheel has a diameter of 11.5 inches. The third gear wheel is adapted to receive a first v-belt. The first v-belt connects the third gear wheel to a fourth gear wheel. The fourth gear wheel has a diameter of five inches and is adapted to receive a v-belt such as the first v-belt. The fourth gear wheel is mounted on a third axle. The third axle extends through a fifth wheel, which in the exemplary embodiment is a flywheel, with a diameter of 15.5 inches, and through a sixth gear wheel. The sixth gear wheel has a diameter of 11.5 inches and is adapted to receive a v-belt such as a second v-belt.

In the exemplary embodiment, an alternator is provided on which is mounted an alternator pulley wheel. In order to generate electricity, the alternator pulley wheel must rotate about 1100 times per minute (1100 revolutions per minute—1100 RPMs). The exemplary embodiment multiplies each revolution of the pedals and the first gear wheel according to the diameter ratios of the various gear wheels and the alternator pulley wheel. As described in further detail below, the exemplary embodiment multiplies each revolution of the pedals and the first gear wheel by 12.91 times at the alternator pulley wheel. Thus, when a person rotates the pedals at approximately 86 revolutions per minute, the alternator pulley wheel revolves approximately 1100 times per minute. The exemplary embodiment produces electrical energy through the alternator, stores the energy in a battery, and provides electrical energy for use by a 110/120 AC current appliance through an inverter.

In alternative embodiments, it would be possible to eliminate the exemplary flywheel; only five gear wheels plus the alternator pulley wheel could be provided. It would also be possible to further reduce the number of gear wheels. However, in order to produce 1100 RPMs, an embodiment with less than five or six gear wheels would feature larger gear wheels and/or would require more power to overcome higher torque.

The exemplary embodiment of the present invention provides a device for converting human power to electrical power. With reference to FIG. 17, the exemplary device comprises: a plurality of gear wheels (e.g., 1, 2, 3, 4, 5 and 6) interconnected with a plurality of interconnection means (e.g., 12, 13, and 14); a first axle (9), said first axle (9) disposed through an opening in a center of a first gear wheel (1) of the plurality of gear wheels; a first pedal (18) mounted on a first pedal arm (17) and a second pedal (18) mounted on a second pedal arm (17), each pedal arm (17) mounted on opposing ends of the first axle (9); a second gear wheel (2) of the plurality of gear wheels interconnected to the first gear wheel (1) with a first interconnection means (12) of the plurality of interconnection means; an alternator (8) interconnected to one of the gear wheels (e.g., 6) of the plurality of gear wheels; a battery (22); and an inverter (27).

In the exemplary embodiment, the alternator is interconnected to one of the gear wheels of the plurality of gear wheels with one of the plurality of interconnection means. However, in a yet further alternative exemplary embodiment (sometimes referred to herein as the “PMG embodiment” or as the “exemplary PMG embodiment”), the alternator is integral to one of the gear wheels of the plurality of gear wheels. In the PMG embodiment, the gear wheel to which the alternator is integral comprises a permanent magnet generator assembly.

The exemplary embodiment of the present invention further provides a device for converting human power to electrical power that comprises: an alternator; an alternator pulley wheel mounted on the alternator; a battery for storing direct current electrical energy; an inverter for converting direct current electrical energy into alternating current electrical energy; a manually-operated first gear wheel comprising a center opening; a second gear wheel, a third gear wheel, a fourth gear wheel, a fifth gear wheel, and a sixth gear wheel; a first axle disposed through the manually-operated first gear wheel center opening; a second axle disposed through a center opening in the second gear wheel and through a center opening in the third gear wheel such that the second gear wheel and the third gear wheel are mounted on the second axle; third axle disposed through a center opening in the fourth gear wheel, and through a center opening in the fifth gear wheel, and through a center opening in the sixth gear wheel such that the fifth gear wheel is mounted on the third axle between the sixth gear wheel and the fourth gear wheel; a first manual-operation means mounted to a first end of the first axle and a second manual-operation means mounted to a second end of the first axle; a first interconnecting means interconnectably mounted to the manually-operated first gear wheel, said first interconnecting means interconnecting the manually-operated first gear wheel to the second gear wheel; a second interconnecting means interconnectably mounted to the third gear wheel, said second interconnecting means interconnecting the third gear wheel to the fourth gear wheel; and a third interconnecting means interconnectably mounted to the sixth gear wheel, interconnecting the sixth gear wheel to the alternator pulley wheel.

The exemplary embodiment further provides an adapter for connecting rotary-motion exercise equipment to mechanically operate a device for converting mechanical power to electrical power, said adapter comprising: a shaft; a shaft sleeve wherein said shaft sleeve is adapted for connection to an axle for mechanically operating the mechanical conversion device; and an adjustable chuck adapted for fastening on to a rotary axle of a rotary-motion exercise device.

The exemplary embodiment further provides a method for converting mechanical power to electrical power, said method comprising: mounting a flywheel with a centrifugally-weighted outer rim to an alternator; mounting an alternator pulley wheel to the alternator; and connecting one of a plurality of interconnected gear wheels to the alternator pulley wheel.

The exemplary embodiment further provides a pedal for operating a rotary motion device, said pedal comprising: an oblong rim adapted for receiving a sole of a human foot or shoe, said oblong rim having a perimeter, a front end, a back end, a first side and a second side; and a centered cross-piece that extends from a center point on the first side of the oblong rim to a center point on the second side of the oblong rim, said cross-piece forming a first space between the cross-piece and the front end adapted for receiving four fingers of a human hand, said cross-piece forming a second space between the cross-piece and the back end adapted for receiving a thumb of a human hand.

FIG. 1 is an exploded perspective view of exemplary gear box transmission 100 components of an exemplary device for converting human power, or mechanical power, to electrical power, in an exemplary embodiment of the present invention.

As depicted in FIG. 1, an alternator 8 is provided. In the exemplary embodiment, alternator 8 is a Chevrolet 350 V-8, 12-volt alternator.

It will be understood by someone with ordinary skill in the art that use in the exemplary embodiment of a 12-volt alternator is illustrative and not a limitation of the invention. For example, in one alternative embodiment, a 16-volt alternator could be used.

As depicted in FIG. 1, alternator 8 further comprises an alternator pulley wheel 7 mounted to alternator 8. In the exemplary embodiment, alternator pulley wheel 7 is a factory-set alternator v-belt pulley wheel with a 3.5 inch outer diameter.

The term “outer diameter” as used herein means the diameter measured from a point on the exterior perimeter of the subject component, such as a pulley, or a wheel, to a point on the opposite side of the exterior perimeter of the subject component.

It will be understood by someone with ordinary skill in the art that use in the exemplary embodiment of pulleys and wheels with particular inner and outer diameters described herein are illustrative and are not a limitation of the invention. In alternative embodiments, different inner- and outer-dimensioned pulleys and wheels could be used. However, as will be understood by someone with ordinary skill in the art, use of different inner- and outer-dimensioned pulleys and wheels could vary the gear ratios described in more detail below and could therefore impact the human-to-electrical power conversion ratios described in more detail below.

It will be understood by someone with ordinary skill in the art that the term wheel is sometimes used herein to refer to gear wheels. Gear wheels in the exemplary embodiment are identified in the figures as wheel 1, wheel 2, wheel 3, wheel 4, wheel 5, wheel 6, and an alternator pulley wheel 7. References to wheel 1, first geared sprocket wheel 1, manually-operated first gear wheel 1, and the like, will be understood to mean reference to gear wheel 1; references to wheel 2 will be understood to mean reference to gear wheel 2; references to wheel 3 will be understood to mean reference to gear wheel 3; references to wheel 4 will be understood to mean reference to gear wheel 4; references to wheel 5 and/or to flywheel 5 will be understood to mean reference to gear wheel 5; references to wheel 6 will be understood to mean reference to gear wheel 6; Wheels 20, such as depicted in, e.g., FIG. 2A, are transport wheels.

It will be further understood by someone with ordinary skill in the art that description of a particular type of gear Wheel for a particular component of the exemplary embodiment is illustrative and non-limiting. For example, in the exemplary embodiment, as described further below, wheels 1 and 2 are geared sprocket wheels; wheels 3, 4 and 6 are pulley gear wheels; wheel 5 is a flywheel. Other types of gear wheels could be used in alternative embodiments. For example, in an alternative embodiment, wheels 1 and 2 could be pulley gear wheels; wheels 3, 4 and 6 could be geared sprocket wheels; flywheel 5 could be adapted to receive a pulley v-belt.

As will be discussed in more detail below, as depicted in FIGS. 11, 12, and 2A, alternator 8 is connected to a battery 22 for storing direct current electrical energy; battery 22 is connected to an inverter 27 for converting direct current electrical energy into alternating current electrical energy.

Returning with reference to FIG. 1, the exemplary embodiment of the present invention further provides a first wheel 1. In the exemplary embodiment, first wheel 1 is a geared sprocket (40B72) wheel with a twelve inch outer diameter.

In the exemplary embodiment, geared sprocket wheel 1 comprises an opening 41 disposed at the center of geared sprocket wheel 1, such as through which an axle can be inserted. In the exemplary embodiment, opening 41 has a three-quarter inch diameter; geared sprocket wheel 1 has an inner diameter of 0.75 inches.

The term “inner diameter” as used herein refers to the diameter of an opening in the center of a wheel, such as through which an axle can be inserted.

In the exemplary embodiment, a main drive axle 9 is inserted through opening 41. A first mechanical-operation means (see e.g., elements 17 and 18 in FIG. 2A) is mounted to one end of main drive axle 9. A second mechanical-operation means (see e.g., elements 17 and 18 in FIG. 2B) is mounted to the opposing end of main drive axle 9. In the exemplary embodiment depicted in FIG. 1, the first and second mechanical-operation means each comprise a foot pedal 18 mounted on a pedal arm 17, which is in turn mounted on main drive axle 9 using three 0.75 inch inner diameter inset bearings 16A, 16B, and 16C (See, e.g., FIGS. 15, 16, and 17).

It will be understood by someone with ordinary skill in the art that use in the exemplary embodiment of manually-operated foot-pedals as mechanical-operation means is illustrative and not a limitation of the invention. For example, in the exemplary embodiment, as is further described below, manual-operation means 17 and 18 can also be hand-operated. In alternative embodiments, pedals could be provided that would be hand-operated but not foot-operated. In a further alternative embodiment, elliptical-exerciser pedals 78/77 could be used (see, e.g., FIG. 14). In a yet further alternative embodiment, stair-stepper pedals could be used. For alternative embodiments using manual-operation means that do not operate in a circular motion, an adapter between such manual-operation means and axle 9 would be provided.

In the exemplary embodiment, with reference to FIGS. 12,15 and 16, an adapter 79 is provided for connecting the exemplary embodiment to rotary motion exercise equipment, e.g., an exercise bicycle. Adapter 79 would be used as an alternative to manual-operation means 17 and 18.

Axle 9 would also be provided with a keyway groove 9-1 adapted for receiving screws 28E. Screw 28E would be used to fasten sleeve 28F to axle 9 by fastening through sleeve screw hole. 28G into axle groove 9-1. Telescoping sleeve 28C would be adjustably connected to shaft 28D by screwing a screw 28E through sleeve screw hole 28L in sleeve 28C into keyway groove 28D-1. Chuck (similar to a Sureline lathe chuck) 28A would be welded on, or machined as part of, telescoping sleeve 28C. Chuck keys 28B would be used to open chuck teeth 28A-1 through 28A-4 of chuck 28A to accept a center axle of a rotary exercise equipment device, such as for example, a center axle of an exercise bicycle wheel. Chuck keys 28B would then be used to tighten chuck teeth 28A-1 through 28A-4 over the subject exercise device center axle. Once chuck teeth 28A-1 through 28A-4 have been tightened, when the center axle of the subject exercise device is rotated, chuck 28A will be rotated, thereby rotating main axle 9, which will in turn rotate wheel 1 and the remainder of the gear box transmission 100.

When more power is being generated through alternator 8 than is used through inverter 27, the power is stored in battery 22.

FIG. 12 is block diagram of exemplary electrical components of the exemplary embodiment of the present invention. As depicted in FIG. 12, the gear-to-gear transmission assembly/gear box transmission 100 is connected to the alternator 8, which is in turn connected, with a fuse 62 and an on/off switch 67, to battery 22, which is in turn connected to inverter 27. A voltmeter gauge 23 and a battery level meter 30 could be provided for readings. As depicted in FIG. 12, a household device or other appliance needing 110/120 household AC current could be connected to and run from electrical energy/power provided through inverter 27. Alternatively, battery 22 could also provide 12-volt output 38 for connection to devices, such as, for example, 12-volt automotive devices to power such devices.

As depicted in FIG. 12, human power 28 could be used to operate the gear box transmission 100 via foot pedals (specifically, a foot pedal 18 mounted on a pedal arm 17), via a stair-stepper mode 77, 78, or via an adapter 79 that would adapt rotary gym equipment, such as exercise bicycles, to power the device.

In the exemplary embodiment, it should be noted that the “foot” pedals 18 are adapted for use as either foot pedals, in which case a human foot would rest on top of the pedal, or as a hand pedal. With reference to FIG. 2E, each pedal of the exemplary embodiment provides a central cross-piece 18-2 which is adapted for receiving an arch of a human foot, or a palm of a human hand. A first opening 18-1 is adapted for receiving four fingers (index, middle, ring, and little fingers) of the human hand. A second opening 18-3 is adapted for receiving a thumb of the human hand. An inwardly sloping (sloping downwardly from the exterior perimeter 18-5 toward the center cross-piece 18-2) oblong ring 18-4 for cradling a ball and a heel of a human foot.

As depicted in e.g., FIGS. 2C, 2D, 2F and 17, the entire gear-to-gear transmission assembly/gear box transmission 100 is housed in the exemplary embodiment in a housing 24. As depicted in FIGS. 2A, 2B and 17, the entire gear-to-gear transmission assembly/gear box transmission 100 is mounted on a structural grid framework 19. Wheels 20 are mounted on structural grid framework 19 so that the entire device can be rolled on wheels 20. A handle 81 is provided. Most of the weight of the exemplary device is mounted near the wheels 20. Accordingly, the weight at the handle-end 81 of the device is fairly light. In one embodiment, handle 81 is a telescoping/retractable handle, such as is available for luggage—the telescoping shafts would be held in the framework underneath the device.

In order to use the exemplary device, a human user of the exemplary device could sit in a chair and place the entire housed gear-to-gear transmission assembly 100 in front of the chair. The human user would then place the user's respective feet on the respective exemplary foot pedals 18 and pedal the device in a bicycle-pedaling mode.

In order to generate a 12.5 voltage output on the alternator, approximately 1100 revolutions per minute (RPMs) of the alternator pulley wheel 7 are needed.

If the human user were to then pedal seventy (70) revolutions per minute, the above-described gear-to-gear ratio of the entire assembly (1:12.91) would result in 875 revolutions per minute of the alternator pulley wheel 7.

If the human user were to pedal ninety (90) revolutions per minute, the above-described gear-to-gear ratio of the entire assembly (1:12.91) would result in 1125.9 revolutions per minute of the alternator pulley wheel 7.

Therefore, with a moderate level of pedaling, averaging ninety (90) revolutions per minute or so, the 1100 RPMs necessary to achieve a 12.5 voltage output on the alternator would be achieved.

The revolutions per minute of the human user (e.g., 90) are multiplied by the exemplary gear-to-gear transmission assembly 100. The multiplication of power is accomplished by the exemplary ratios of the outer diameters of the various interconnected wheels, including the alternator pulley wheel. Specifically, in the exemplary embodiment, a larger wheel 1 with an outer diameter of twelve (12) inches is used to drive, via the geared sprocket chain 12, a smaller wheel 2 with an outer diameter of only seven (7) inches. It is the outer diameter ratio of the two wheels (12/7) that results in the multiplication of one revolution of wheel 1 resulting in 1.71 revolutions of wheel 2.

In the exemplary embodiment, wheel 2 with an outer diameter of only seven (7) inches, is connected via drive axle 10 to a much larger wheel 3 with an outer diameter of 11.5 inches. By virtue of the axle 10 connection of smaller wheel 2 to larger wheel 3, each revolution of wheel 1 results in 1.71 revolutions of not only wheel 2, but also of larger wheel 3.

In the exemplary embodiment, larger wheel 3 is then connected with v-belt 13 to smaller wheel 4 with an outer diameter of only five (5) inches. The outer diameter ratio of wheel 3 as compared to wheel 4 (11.5/5) results in the multiplication of one revolution of wheel 3 resulting in 2.3 revolutions of wheel 4. Therefore, for each revolution of wheel 1, wheel 4 revolves 3.93 times (1.71 times 2.3).

In the exemplary embodiment, smaller wheel 4 is connected via drive axle 11 to both flywheel 5 and larger wheel 6. By virtue of the drive axle 11 connection of smaller wheel 4 to larger wheel 6, for each revolution of wheel 4, wheel 6 also revolves one time. In the exemplary embodiment, wheel 6 has an outer diameter of 11.5 inches. Wheel 6 is connected to alternator pulley wheel 7 via v-belt 14. Alternator pulley wheel 7 has an outer diameter of only 3.5 inches. Therefore, for each complete revolution of wheel 6, alternator pulley wheel 7 will revolve 3.285 times (11.5/3.5=3.285). Therefore, for each complete revolution of wheel 1, alternator pulley wheel 7 will revolve 12.91 times (1.71 times 2.3 times 3.285=12.91).

It will be understood by someone with ordinary skill in the art that varying the outer diameters of the various interconnected wheels and the alternator pulley wheel could result in higher or lower RPMs as the case may be.

For example, in an alternative embodiment, fifth wheel flywheel 5 could be modified to itself accept an interconnecting means, such as a v-belt. In such an embodiment, a v-belt would interconnect fifth wheel flywheel 5 to alternator pulley wheel 7. Such a modification would result in an overall turn ratio of 1:16.51 for the gear-to-gear transmission assembly 100. The 1:16.51 ratio would achieve 1320.80 RPMs for 80-pedal-revolutions of wheel 1 per minute.

In a further alternative embodiment, wheel 6 would be provided with a sixteen inch outer diameter; the flywheel would be removed from between wheel 6 and wheel 4 and would be mounted instead to alternator pulley wheel 7.

Compactness of the gear box transmission 100 is achieved in the exemplary embodiment by pairing large wheels with smaller wheels which are in turn connected via drive axles to larger wheels. As can be seen in, e.g., FIG. 3, the outer rim 1-1 of wheel 1 is separated from the outer rim 2-1 of wheel 2 by a distance 48.

FIGS. 13A and 13B depict compact layering of the three gear stages. (stages one, two and three) of the exemplary embodiment. FIG. 13A is a right side plan view depicting exemplary layers of gears in the exemplary embodiment of the present invention. FIG. 13B is a left side plan view depicting exemplary layers of gears in the exemplary embodiment of the present invention.

Because the outer diameter of wheel 3 (in the exemplary embodiment, 11.5 inches) is smaller than the diameter of wheel 1 (in the exemplary embodiment, 12 inches), and because the outer rim 1-1 of wheel 1 is separated from the outer rim 2-1 of wheel 2 by a distance 48 (see FIG. 3), side-by-side mounting of wheel 3 on a common axle (10) with wheel 2 does not result in an interfering overlap with respect to the position of wheel 1 or with mechanical-operating means attached to an axle (9) mounted in wheel 1.

Similarly, the assembly of wheels 4, 5 and 6 on a single axle 11, and aligning the rim of wheels 4 and 3 for receipt of v-belt 13 does not result in any interference as between wheels 3, 4, 5 and/or 6, or with respect to wheels 2 and 1.

The exemplary device and its gear ratios balance high front-end torque with high-speed low torque at the back-end of the device. Alternative gear ratios could be used without departing from the spirit of the invention, but could result in alternative front-end torque or back-end speed. (Reference to the front-end of the device is meant to refer to the wheel 1/handle 81 end of the device; reference to the back-end of the device is meant to refer to the alternator 8/battery 22 end of the device).

A yet further alternative exemplary embodiment (sometimes referred to herein as the “PMG embodiment” or as the “exemplary PMG embodiment”) of the present invention is described. In the exemplary PMG embodiment of the present invention, instead of a simple flywheel gearwheel (element 5, e.g., FIG. 1) and a separate, self-contained alternator (element 8, e.g., FIG. 1) (such as an automotive alternator) as was employed in the exemplary embodiment, an exemplary permanent magnet generator (also sometimes referred to herein as a “PMG”) assembly 300 such as is depicted in FIGS. 21 and 22, is used. In the exemplary PMG embodiment of the present invention, a portion of the permanent magnet generator assembly 300 acts as one of the gear wheels. Further, the permanent magnet generator assembly 300, when operated, generates electrical power in the form of alternating current (AC). Therefore, because it generates electrical power in the form of alternating current, the permanent magnet generator assembly 300 is an “alternator”. Accordingly, as compared to a simple flywheel gearwheel (element 5, e.g., FIG. 1) and a separate, self-contained alternator (element 8, e.g., FIG. 1) (such as an automotive alternator) as was employed in the exemplary embodiment, in the exemplary PMG embodiment of the present invention, the alternator is integral to the gear wheel comprising, in part, the permanent magnet generator assembly 300.

The permanent magnet generator assembly 300 will generate low voltage, “three phase” AC. In the exemplary PMG embodiment of the present invention, as will be discussed further below, the alternating current generated by operating the permanent magnet generator assembly 300 will be changed into “direct current” (DC) for charging a 12 volt battery (See, e.g., element 243, FIG. 18).

FIG. 18 is an exploded perspective view of further alternative exemplary gear box transmission components, including the exemplary permanent magnet generator assembly 300, of the further alternative exemplary device for converting human power, or mechanical power, to electrical power in the exemplary PMG embodiment of the present invention.

Returning with reference to FIGS. 21 and 22, the exemplary permanent magnet generator assembly element 300 comprises a stator 231 and two rotors (217 a and 217 b). (Reference herein to a rotor 217 will be understood to apply to each of the two rotors 217 a and 217 b).

The stator 231 of the exemplary PMG assembly 300 comprises a high-temperature epoxy into which is imbedded a plurality of coils 232 of wire; a center hole 306 of stator 231 is provided. In the exemplary permanent magnet generator assembly 300, eight coils 232 of wire are provided. In the exemplary PMG assembly 300, each coil 232 comprises two-hundred (200) winds of 16-gauge coated magnet wires. Each coil 232 forms substantially a circle with a center point 303; each coil 232 measures approximately one-and-one-half inches in diameter. In the exemplary PMG assembly 300, the coils 232 are imbedded in the stator equidistant from a center point 301 of the stator 231 so that the center point 303 of each coil 232 is substantially the same distance from center point 301 of the stator 231. The distance that the center point 303 of a coil 232 is positioned from center point 301 will be referred to as “Radius A.”

In the exemplary PMG assembly 300, each coil 232 is separated from a coil 232 on either side by a substantially standard distance, referred to herein as “Distance C.” In the exemplary PMG assembly 300, the center point 303 of a first coil 232 is Distance C from the center point 303 of each coil 232 on either side of the first coil 232.

In the exemplary PMG assembly 300, the stator 231 is encased around its perimeter in an aluminum stator casing 237; the exemplary aluminum stator casing 237comprises aluminum that is approximately one-eighth of an inch thick, and is approximately one inch wide.

In the exemplary PMG assembly 300, each rotor 217 comprises a high-temperature epoxy into which is imbedded eight permanent magnets 218. In the exemplary PMG assembly 300, each rotor 217 comprises a disk of epoxy that measures approximately twelve inches in diameter having a center 302. In the exemplary PMG assembly 300, a center hole 308 is provided in each rotor 217.

In the exemplary PMG assembly 300, each permanent magnet 218 comprises a high-quality neodymium magnet measuring approximately one-half inch thick, and one-and-one-half inch in diameter with a center 304. In the exemplary PMG assembly 300, the permanent magnets 218 are imbedded in the respective rotor 217 at a substantially standard distance; the substantially standard distance is measured from the center 302 of the rotor 217 to the respective center 304 of each of the respective permanent magnets 218. The substantially standard distance that the center point 304 of a permanent magnet 218 is positioned from center 302 of the respective rotor 217 will be referred to as “Radius B.”

In the exemplary PMG assembly 300, the permanent magnets 218 are imbedded in the respective rotor 217, alternating face-up poles. For example, as depicted in FIG. 25A, magnets 218-1, 218-3, 218-5 and 218-7 would be imbedded in the epoxy rotor 217 a so that a north pole would be face up; magnets 218-2, 218-4, 218-6 and 218-8 would be imbedded in the epoxy rotor 217 a so that a south pole would be face up. In rotor 217 b, as depicted in, e.g., FIG. 25B, magnets 218-1Q, 218-12, 218-14, and 218-16 would be imbedded in the epoxy rotor 217 b so that a south pole would be face up; magnets 218-11, 218-13, 218-15 and 218-17 would be imbedded in the epoxy rotor 217 b so that a north pole would be face up.

In the exemplary PMG assembly 300, the center 304 of a first permanent magnet 218 is separated from the center 304 of a permanent magnet 218 on either side of the first permanent magnet 218 by a substantially standard distance, referred to herein as “Distance D.” In the exemplary PMG assembly 300, the center 304 of the first permanent magnet 218 is Distance D from the center 304 of each permanent magnet 218 on either side of the first permanent magnet 218.

In the exemplary PMG assembly 300, Distance C is approximately equal to Distance D; Radius A is approximately equal to Radius B. Accordingly, in the exemplary PMG assembly 300, when rotor 217 a is placed (such as depicted, e.g., in FIGS. 18, 21, and 22) so that the magnets 218 of rotor 217 a are facing the magnets 218 of rotor 217 b, and when the magnets 218 of rotor 217 a are aligned with the magnets 218 of rotor 217 b so that the magnets 218 of rotor 217 a are counter-posed to the magnets 218 of rotor 217 b, rotor 217 a is substantially a visual mirror image of rotor 217 b, and vice versa.

Even though when the magnets 218 of rotor 217 a are counter-posed to the magnets 218 of rotor 217 b, rotor 217 a is substantially a visual mirror image of rotor 217 b, the magnets of rotor 217 a must be opposite in face-up pole from the corresponding counter-posed magnets 218 of rotor 217 b. That is, a first magnet 218-1 (See FIG. 25A) of rotor 217 a must attract a second, counter-posed magnet 218-10 (See FIG. 25B) of rotor 217 b.

In the exemplary PMG assembly 300, each rotor 217 is mounted to a respective steel plate 216. In the exemplary PMG assembly 300, the steel plate 216 is made of stainless steel. Stainless steel is used in the exemplary embodiment because it is not magnetic and because it does not spoil the effect of the magnets 218.

In the exemplary PMG assembly 300, each steel plate 216 measures approximately one-quarter inch (¼″) in thickness and measures approximately twelve inches in diameter. In the exemplary PMG assembly 300, each steel plate 216 provides a stop collar 307 that is welded in a center of the respective steel plate 216; each steel plate 216 provides four holes 305 through which bolts can be threaded. In the exemplary PMG assembly 300, the stop collar 307 measures approximately three-quarters of an inch (¾″) in thickness. In the exemplary PMG assembly 300, four fine thread bolts 215 are provided, each measuring approximately one-quarter inch (¼″) in diameter, and measuring approximately three inches (3″) long.

In the exemplary PMG assembly 300, in order to maintain the mirror-image, counter-posed-attraction relationship as described above between the magnets 218 of rotor 217 a and the magnets 218 of rotor 217 b, each rotor 217 is mounted to a respective steel plate 216 to form a rotor 217/steel plate 216 assembly 309 (see, e.g., FIGS. 18, 21, 22, 25A and 25B). Four bolts 215 are fitted through the four respective holes 305 of a first rotor 217/steel plate 216 assembly 309 (see, e.g., FIGS. 18, 21, 22, 25A and 25B), e.g., the assembly 309 comprising rotor 217 b and a respective steel plate 216. The four bolts 215 are slid through four respective spacing bars 236 that are extended through the inside of the perimeter of hole 306 in the stator 231. The ends of the four bolts 215 are then threaded through the four holes 305 in the other rotor/plate assembly 309 (e.g., the assembly 309 comprising rotor 217 a and a respective steel plate 216). The threaded ends of each the four bolts 215 are each secured with a nut 250, such as in the exemplary PMG assembly 300, a one-quarter inch (¼″) nyloc nut 250.

With reference to FIG. 18, in the exemplary PMG assembly 300, a shaft 219 is inserted through the stop collar 307 and hole 308 in a first rotor/plate assembly 309, e.g., rotor 217 a/plate 216, through the center of the hole 306 in the stator 231, and through the hole 308 and stop collar 307 of a second rotor/plate assembly 309, e.g., rotor 217 b/plate 216. A set screw 224 is threaded through each stop collar 307 to hold the shaft 219 in the exemplary PMG assembly 300.

With reference to FIG. 18, each end of shaft 219 is rotatably anchored in opposing sides of aluminum framework casing 201 and 201′ respectively, using a bearing with stop ring 206 on each end of shaft 219.

Continuing with reference to FIG. 18, in the exemplary PMG assembly 300, the stator 231, encased in the aluminum stator casing 237, is bolted using bolts 233 to bolt the casing 237 to an aluminum framework casing floor panel 230 (See also, FIG. 20). Ends 232 a of the coils 232 are attached to block connectors 240 which are in turn connected to bridge rectifiers 239.

With reference to FIG. 20, a first pulley 225, such as a one-and-one-half inch (1½″) V-belt pulley 225, is attached to one exposed end of shaft 219. First pulley 225 is set in place on the exposed end of shaft 219 using a set screw 248. Much of the rest of the further alternative exemplary device is similar in operation to the exemplary embodiment and is described only in overview.

First V-belt pulley 225 is connected with a first V-belt 228 to a second V-belt pulley 226. In the exemplary PMG embodiment, second V-belt pulley 226 measures approximately seven inches (7″) in diameter. A third pulley 221 is connected to V-belt pulley 226 via an upper shaft 229. In the exemplary PMG embodiment, third V-belt pulley 221 measures approximately three inches (3″) in diameter.

Third V-belt pulley 221 is connected via a second V-belt 227 to a fourth V-belt pulley wheel 220. In the exemplary PMG embodiment, fourth V-belt pulley 220 measures approximately 12 inches (12″) in diameter. In the exemplary PMG embodiment, fourth V-belt pulley 220 is attached to a main pedal drive shaft 241. In the exemplary PMG embodiment, main pedal drive shaft 241 is approximately three-quarters of an inch (¾″) in diameter and is milled to accommodate fourth V-belt pulley 220, a set screw 223, and a pedal armature 350.

The further exemplary embodiment of the present invention may be operated by attaching foot pedals (or hand pedals) 18 to the pedal armature 350. FIG. 37 is a perspective view of a foot/hand pedal operable device of the further exemplary embodiment of the present invention.

With reference to FIGS. 19 and 35, the further exemplary embodiment of the present invention may also be operated by attaching elliptical ski/stair-stepper pedals 253 to the pedal armature 350. FIGS. 19 and 35 depict elliptical ski/stair-stepper pedals 253 connected to respective pedal armatures 350. As depicted in FIGS. 19 and 35, an elliptical ski/stair-stepper pedal 253 is further connected to a pivot speedrail fitting 268 with 3 points of attachment which is in turn connected to a ring-welded steel swing bar 260. The ring-welded steel swing bar 260 is attached to a vertical bar 274 for stepper steps. FIGS. 35 and 36 show perspective views of an elliptical ski/stair-stepper pedal operable device of the further exemplary embodiment of the present invention.

A partial parts list for the exemplary PMG embodiment is provided below. The element numbers (also referred to herein as a part number, e.g., element 201 may be alternatively referred to as “part 201” or “Part 201”) listed below will be referenced in one of FIGS. 18 through 39, although the majority of the parts listed below can be viewed in FIG. 18.

Returning with reference to FIG. 18, and with reference to FIG. 20, as human power is applied to pedals (either foot pedals 18 (FIG. 37), or elliptical ski/stair-stepper pedals 253 (FIG. 36)), the main pedal drive shaft 241 will rotate, thereby causing fourth V-belt pulley 220 to rotate. As fourth V-belt pulley 220 rotates, V-belt 227 will cause third V-belt pulley 221 to rotate, causing rotation of second V-belt pulley 228 via upper shaft 229. As second V-belt pulley 228 rotates, first V-belt pulley 225 will rotate via V-belt 228. As first V-belt pulley 225 rotates, PMG shaft 219 will rotate, causing rotation of the exemplary rotor/steel plate assemblies 309 (FIG. 18).

With reference to FIG. 18, as the rotors 217 of the exemplary rotor/steel plate assemblies 309 are rotated, the counter-posed magnets become aligned (although in normal operation, only momentarily) with a respective coil 232 so that magnetic flux passes from a magnet, (e.g., North-pole faced-up magnets 218-1, 218-3, 218-5 and 218-7 respectively) on one rotor, e.g., 217 a, to the counter-posed magnet (e.g., South-pole faced-up magnets 218-10, 218-12, 218-14 and 218-16 respectively) on the other rotor, e.g., 217 b, through the respective coil 232; and from North-pole faced up magnets 218-11, 218-13, 218-15 and 218-17 on, e.g., rotor 217 b, to the counter-posed South-pole faced-up magnets 218-2, 218-4, 218-6 and 218-8 on, e.g., rotor 217 a. As the rotors continue to turn, the magnetic flux passing from one rotor, e.g., 217 a, to the other rotor, e.g., 217 b through a particular coil 232, alternates so that the next pair of counter-posed magnets that are aligned with that coil 232 cause an alternate magnetic flux to pass through the coil 232. The alternating magnetic flux moving through the respective coils 232 of the stator 231 produces electric power in the form of alternating current.

FIG. 38 is a block diagram depicting exemplary electrical components in relation to physical components in the exemplary PMG device in the exemplary PMG embodiment of the present invention. As depicted in FIG. 38, the gear-to-gear transmission assembly/gear box transmission 100′ can be driven by human user input 68 via either bicycle pedal (foot pedal) mode 18, or via stair stepper mode 253. As depicted in FIG. 38, the gear box transmission could be connectable to a gym equipment adapter 79 as was previously described above.

As depicted in FIG. 38, the gear-to-gear transmission assembly/gear box transmission 100′ is connected to the permanent magnet generator assembly 300, which is in turn connected to on/off switch 67, which is in turn connected, via a fuse 62-1, to battery 243. In the PMG embodiment, battery 243 is a 12-volt mini lead-acid battery. As depicted in FIG. 38, battery 243 is a primary storage of the power generated by operating the PMG assembly 300. Battery 243 is connected to a ground 31. Battery 243 is also connectable to a device operable with 12-volt power 38, such as a 12-volt automotive device 39. Battery 243 is connected to a fuse 62-2, which is in turn connected,.via an on/off switch 67-2, to a first 110/120 AC/DC inverter 27 that can convert the 12-volt DC energy to 110/120 AC power for supplying power to a device that operates using 110/120 AC power, such as a household device 32. Battery 243 is also connected, or connectable, to a battery isolator/regulator 333 for charging multiple batteries such as a secondary battery 330. The secondary battery 330 could also be connected, via an on/off switch 67-1, to a second 110/120 AC/DC inverter 27′ that can convert the 12-volt DC energy to 110/120 AC power for supplying power to a device that operates using 110/120 AC power, such as a household device 32′.

FIG. 39 is a schematic diagram depicting exemplary connections between the exemplary PMG assembly 300 and various electrical components of the exemplary PMG device in the exemplary PMG embodiment of the present invention. As depicted in FIG. 39, ends 232 a of the coils (element 232 in, e.g., FIG. 18) are attached to block connectors 240 which are in turn connected to bridge rectifiers 239. The alternating current generated by operating the permanent magnet generator assembly 300 is changed via the bridge rectifiers 239 into ‘direct current’ (DC) for charging a 12-volt battery 243. The bridge rectifiers 239 are connected to the battery 243 via an on/off switch 67, and a fuse 62-1. A voltmeter 23 is provided to measure the charge to battery 243. Battery 243 is connected to a first 110/120 AC inverter 27 (such as a 400 W inverter) to run devices that are operable via 110/120 AC power. An isolator diverter 333 is connected, or connectable, to battery 243 via fuse 62-2. Isolator diverter 333, when connected to charged battery 243, can be used to charge secondary batteries, e.g., 330, which can in turn be connected to a second 110/120 AC inverter 27′ (such as a 400 W inverter) to run devices that are operable via 110/120 AC power. As depicted in FIG. 38, a converter 345 could be connected to battery 243 to convert input 110/120 AC current to 12-volt direct current to allow input to charge battery 243.

As compared to the exemplary embodiment which required that the alternator pulley wheel must rotate about 1100 times per minute in order to generate electricity, the exemplary PMG embodiment with the exemplary PMG assembly 300 recognizes electricity generation with very low RPMs. Indeed, the exemplary PMG embodiment with the exemplary PMG assembly 300 recognizes electricity generation following early rotation of the rotors.

Other features of the invention are implicit in the above-provided description and/or are depicted and/or implicit in the accompanying Figures.
